1. What Is a Read-Only Domain Controller? RODCs host read-only partitions of the AD DS database, only accept replicated changes to Active Directory, and never initiate replication RODCs: Cannot hold operation master roles or be configured as replication bridgehead servers Can be deployed on servers running Windows Server 2008 Server core for additional security RODCs provide: Additional security for branch office with limited physical security Additional security if applications must run on a domain controller RODC

3. RODC features Read-only Active Directory database  Except for account passwords, an RODC holds all the Active Directory Domain Services (AD DS) objects and attributes that a writable domain controller holds.  Clients are not able to write changes directly to the RODC.  Lightweight Directory Access Protocol (LDAP) applications that perform a Write operation are referred to a writable domain controller in a hub site.

4. Preparing to Install the RODC Before installing an RODC: Ensure that the domain and forest is at a Windows Server 2003 functional level Ensure a writeable domain controller running Windows Server 2008 is available to replicate the domain partition Run ADPrep /rodcprep to enable the RODC to replicate DNS partitions Run ADPrep /domainprep in all domains if the RODC will be a global catalog server

5. Installing a Read-Only Domain Controller Using an Unattend File Run adprep /rodcprep if necessary Create RODC account:  dcpromo.exe /CreateDCAccount /unattend:"Path to answer file" Attach server to RODC account:  dcpromo.exe /UseExistingAccount:Attach /unattend:"Path to answer file"

9. Module 4: Using Windows Deployment Services

10. Module Overview Windows Deployment Services Working with the WIM format

11. Lesson 1: Windows Deployment Services History of Deployment Windows Deployment Services Introduction Benefits of WDS WDS Environment WDS Server and Client Windows Pre-Installation Environment with WDS Multicasting WDS Management

12. History of Deployment Previous Solutions: RIS Windows Deployment Services enables you to deploy Windows operating systems You can use it to set up new computers by using a network-based installation. You do not have to be physically present at each computer and you do not have to install each operating system directly from a CD or DVD

13. What is Windows Deployment Services? The Windows Deployment Services role in Windows Server 2008 is the updated and redesigned version of Remote Installation Services (RIS). You can use it to set up new computers by using a network- based installation.

14. WDS - Components  Server components.  Pre-Boot Execution Environment (PXE) server  Trivial File Transfer Protocol (TFTP) server  Shared Folder – Image Repository  Client components.  A graphical user interface that runs within the Windows Pre-Installation Environment (Windows PE).  When a user selects an operating system image, the client components communicate with the server components to install the image  Management components.  These components are a set of tools that you use to manage the server

15. Changes From RIS  The ability to deploy Windows Vista and Windows Server 2008.  Windows PE is the boot operating system.  Image-based installation, using the Windows image (.wim) file.  The ability to transmit data and images using multicast functionality.  An extensible and higher-performing PXE server component.  A new graphical user interface on the client that you can use to select images.  The Windows Deployment Services Microsoft Management Console (MMC) snap-in on the server, which enables you to manage all Windows Deployment Services features.

16. Windows Imaging Format (WIM) WIM is a file-based disk image format that was introduced in Windows Vista. WIM files are compressed packages that contain a number of related files. The format of a WIM file is optimized for maximum compression Images are File based not Sector Based Single Instancing The WIM image format allows you to service an image offline

17. ImageX ImageX is the command-line tool used to create, edit and deploy Windows disk images in the Windows Imaging Format. It is distributed as part of the free Windows Automated Installation Kit (WAIK).

18. Windows Preinstallation Environment (Windows PE) 2.0 WinPE is Bootable and Light weight version of Windows Can use to start a PC from USB or CD/DVD Traditionally used by large corporations and OEMs (to preinstall Windows client operating systems to PCs during manufacturing) Now widely available free of charge via the Windows Automated Installation Kit (WAIK).

19. Windows System Image Manager (SIM) Tool Used to create unattended windows setup answer files It replaces setup manager

20. SYSPREP Used to generalize a reference computer installation Image Removes those settings that should not be shared These settings are computer name, SID, Domain membership, Product Key etc

26. Summary Windows Deployment Services is a server-based technology for deploying Windows images onto bare-metal computers. When a PXE-enabled computer that has no operating system boots, it contacts the PXE server on your WDS server, obtains an IP address, and downloads the WDS client. The WDS client then displays a boot menu, which presents a list of operating systems that can be installed on the system. A boot image is a Windows image (.wim) file you can use to boot a bare- metal client computer to begin the deployment of an operating system to the computer. When deploying images with WDS, you can use the default boot image from the \sources folder on the Windows Server 2008 DVD. An install image is an image of the Windows Vista or Windows Server 2008 operating system itself that you plan on deploying onto the client computer. The simplest way of using WDS is to deploy the default install image included in the \sources folder on your Windows Server 2008 product DVD. A capture image is a special boot image that you use to boot a master computer and upload an image to a WDS server.

Other command-line tools including BCDEdit, Bootsect, DiskPart, Drvload, and others that can be used to automate various aspects of deployment

30. Tools Previous and Later

31. Windows SIM Distribution Share – This pane displays the currently opened distribution share. You also use this pane to create new distribution shares, add items to the share, and close an open share. Windows Image – This pane displays the currently opened Windows Image (.wim) file. You must open a.wim file before you can create an answer file. Answer File – This pane is where you create a new answer file and add components (groups of operating system settings) and packages (includes software updates, language packs, and so on) to answer file. Properties – This pane lets you assign values to the component or package that is currently selected in your Answer File pane. Messages – This pane displays errors, warnings and information messages concerning the syntax and structure of your answer file when you try and validate your answer file.

32. Configuration Passes Configuration passes are the phases of a Windows® installation during which you can customize an image. Windows unattended installation settings can be applied in one or more configuration passes, depending upon the setting you use.

33. Configuration Passes Pass 1 windowsPE  Configuration pass are used to configure how the Windows Preinstallation Environment (Windows PE) behaves  Pass are found under the x86_Microsoft-Windows-Setup component Pass 2 offline servicing  Settings for this configuration pass can be used to do things like add additional drivers, security updates, hotfixes, language packs, and other packages to your Windows Image (WIM) file  Pass are found under x86_Microsoft-Windows-Shell- Setup

34. Configuration Passes

35. 1.Run Windows Setup and specify an answer file. Windows Setup starts. 2.The windowsPE configuration pass runs. Settings in the section of an answer file are processed. - configuring disk partitions or enabling dynamic updates. 3.After the Windows image is copied to the hard disk, the offlineServicing configuration pass runs. Any settings in the and section of an answer file are applied -install or remove packages, language packs, or device drivers. 4.The system restarts and Windows Setup runs the specialize configuration pass. At this point, settings in the section of the answer file are processed. 5.After Windows Setup completes, the computer restarts. Then, the oobeSystem configuration pass runs and settings in the section of an answer file are processed

40. Managing Disks

41. What Is Disk Management? A snap-in located in Computer Management Use to view disk information and perform disk management tasks on local and remote computers To Access diskmgmt.msc

42. Basic Disk MBR  4 Primary  Extended GUID  128 Primary  Recommended for 2TB and Above  64 Bit Systems

43. Basic Disks vs. Dynamic Disks DiskBenefits Basic disks Use to create segregated space to organize data Can be divided into up to 4 primary partitions, or up to 3 primary partitions and one extended partition Dynamic disks Use to create volumes that span multiple disks No limit on the number of volumes per disk Use to create fault-tolerant disks that ensure data integrity when hardware failures occur

44. Dynamic Disks Dynamic disk contains dynamic volumes that you create in the Disk Management console After converting basic disk to dynamic disk we can create Volumes for speed and Fault tolerance Dynamic disk changes does not need a reboot Disk Management is used to upgrade a basic disk to a dynamic disk Upgrading to a dynamic disk is a one-way process. It's possible to convert a dynamic disk with volumes to a basic disk, But, you'll lose all your data

45. Dynamic Disks Using Dynamic Disks you can create the following volumes:  Simple  Spanned  Mirrored – (RAID 1)  Striped – (RAID 0)  Stripe set with Parity (RAID 5) RAID is commonly implemented for both performance and fault tolerance. With RAID, you can choose to assemble disks to provide fault tolerance, performance, or both, depending on the RAID level that you configure

46. Simple Volume If using single disk, A simple volume is the only volume type you can create Can extend simple volumes that are not system or boot volumes You can extend a simple volume onto additional dynamic disks to create a spanned volume No Fault tolerance Can use the NTFS file systems Can be extended

47. Spanned Volume Combining Disk space from two or more Hard Disks. Can use different amount of disk space Can’t install OS on a spanned Volume No Fault tolerance Can contain up to 32 Physical disks No Performance Gain Spanned volumes cannot be mirrored or striped 3994 MB Unallocated New Volume (G) 100 MB NTFS Healthy Disk 1 Dynamic 4094 MB Online 3994 MB Unallocated New Volume (G) 100 MB NTFS Healthy Disk 2 Dynamic 4094 MB Online Free space combined into one logical volume Free space combined into one logical volume

48. Striped Volume Combines areas of free space from multiple hard disks into one logical volume Unlike a spanned volume, data is written to all physical disks in the volume at the same rate Created using minimum two and Maximum of 32 disks Best Read and Write performance The data is divided into 64KB parts and written to each disk No fault tolerance Recommended to use Identical Physical Disks. Same Size, Transfer Rate and Manufacturer and model

49. What Is a Striped Volume? Data written across all disks in 64 KB units 64 KB Striped Volume 3994 MB Unallocated New Volume (G) 100 MB NTFS Healthy Disk 1 Dynamic 4094 MB Online 3994 MB Unallocated New Volume (G) 100 MB NTFS Healthy Disk 2 Dynamic 4094 MB Online Free space combined into one logical volume Free space combined into one logical volume 64 KB

50. Mirrored Volume Created Using two Physical disks Same amount of space on both disks Data is written and synchronized on another disk Boot and system Partition can be mirrored Remember to edit boot.ini, if using mirrored volume on Boot partition and if it fails Fault tolerant

51. RAID 5 Volume Fault-tolerant striped volume Space on three or more disks is combined RAID 5 write operations are slower High availability, one disk may fail, but the Logical Drive with the data is still available Parity is a method of error checking that uses an exclusive OR operation to create a checksum for each block of data written to the disk. The Parity information allows one disk to fail and the volume be still operational

52. Mounted Volume Method of creating a volume that can be referenced by a name. The mounted volume is associated through a Folder Folder need to be in NTFS and Empty

53. Stop Mirroring  Delete the volume - If you delete the volume, the volume and all the information it contains is removed. The resulting unallocated space is then available for new volumes.  Remove the mirror - If you remove the mirror, the mirror is broken and the space on one of the disks becomes unallocated. The other disk maintains a copy of the data that had been mirrored, but that data is of course no longer fault-tolerant.  Break the mirror - If you break the mirror, the mirror is broken but both disks maintain copies of the data. The portion of the mirror that you select when you choose Break Mirror maintains the original mirrored volume’s drive letter, shared folders, paging file, and reparse points. The secondary drive is given the next available drive letter.

54. Shrinking Volume Can Decrease the space used by simple or spanned volume Can be used to increase the amount of unallocated space on a disk Files are automatically relocated on the disk to create the new unallocated space
